Abstract

L'invention concerne un appareil pour former un article cupuliforme de forme tridimensionnelle, à partir d'une plaque métallique généralement plane. Ledit appareil comprend un moule ayant une surface de formage dont le contour correspond à ladite forme tridimensionnel, et présentant des bord correspondant aux contours de l'article, définis par la parois latérales sensiblement perpendiculaires au plan de formage; un dispositif de formage comportant un bac à liquide et des paires d'éléments de décharge électrique placés dans le liquide, comprenant une ouverture faisant face au moule, de sorte qu'une onde de pression soit transmise du liquide à la plaque métallique; et des circuit de décharge électrique pour décharger un courant électrique bref et intense à travers les paires d'éléments de décharge électrique générant une étincelle électrique ou une fracturation dans le liquide, de sorte que du plasma, de la vapeur ou les deux soient formés.
